pub struct Ipv6Net { /* private fields */ }
Expand description

An IPv6 network address.

See IpNet for a type encompassing both IPv4 and IPv6 network addresses.

Textual representation

Ipv6Net provides a FromStr implementation for parsing network addresses represented in CIDR notation. See IETF RFC 4632 for the CIDR notation.

Examples

use std::net::Ipv6Addr;
use ipnet::Ipv6Net;

let net: Ipv6Net = "fd00::/32".parse().unwrap();
assert_eq!(Ok(net.network()), "fd00::".parse());

Implementations

Creates a new IPv6 network address from an Ipv6Addr and prefix length.

Examples
use std::net::Ipv6Addr;
use ipnet::{Ipv6Net, PrefixLenError};

let net = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24);
assert!(net.is_ok());

let bad_prefix_len = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 129);
assert_eq!(bad_prefix_len, Err(PrefixLenError));

Creates a new IPv6 network address from an Ipv6Addr and netmask.

Examples
use std::net::Ipv6Addr;
use ipnet::{Ipv6Net, PrefixLenError};

let net = Ipv6Net::with_netmask(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), Ipv6Addr::from(0xffff_ff00_0000_0000_0000_0000_0000_0000));
assert!(net.is_ok());

let bad_prefix_len = Ipv6Net::with_netmask(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), Ipv6Addr::from(0xffff_ff00_0000_0000_0001_0000_0000_0000));
assert_eq!(bad_prefix_len, Err(PrefixLenError));

Returns a copy of the network with the address truncated to the prefix length.

Examples
assert_eq!(
    "fd00::1:2:3:4/16".parse::<Ipv6Net>().unwrap().trunc(),
    "fd00::/16".parse().unwrap()
);

Returns the address.

Returns the prefix length.

Returns the maximum valid prefix length.

Returns the network mask.

Examples
let net: Ipv6Net = "fd00::/24".parse().unwrap();
assert_eq!(Ok(net.netmask()), "ffff:ff00::".parse());

Returns the host mask.

Examples
let net: Ipv6Net = "fd00::/24".parse().unwrap();
assert_eq!(Ok(net.hostmask()), "::ff:ffff:ffff:ffff:ffff:ffff:ffff".parse());

Returns the network address.

Examples
let net: Ipv6Net = "fd00:1234:5678::/24".parse().unwrap();
assert_eq!(Ok(net.network()), "fd00:1200::".parse());

Returns the last address.

Technically there is no such thing as a broadcast address for IPv6. The name is used for consistency with colloquial usage.

Examples
let net: Ipv6Net = "fd00:1234:5678::/24".parse().unwrap();
assert_eq!(Ok(net.broadcast()), "fd00:12ff:ffff:ffff:ffff:ffff:ffff:ffff".parse());

Returns the Ipv6Net that contains this one.

Examples
let n1: Ipv6Net = "fd00:ff00::/24".parse().unwrap();
let n2: Ipv6Net = "fd00:fe00::/23".parse().unwrap();
let n3: Ipv6Net = "fd00:fe00::/0".parse().unwrap();

assert_eq!(n1.supernet().unwrap(), n2);
assert_eq!(n3.supernet(), None);

Returns true if this network and the given network are children of the same supernet.

Examples
let n1: Ipv6Net = "fd00::/18".parse().unwrap();
let n2: Ipv6Net = "fd00:4000::/18".parse().unwrap();
let n3: Ipv6Net = "fd00:8000::/18".parse().unwrap();

assert!(n1.is_sibling(&n2));
assert!(!n2.is_sibling(&n3));

Return an Iterator over the host addresses in this network.

Examples
let net: Ipv6Net = "fd00::/126".parse().unwrap();
assert_eq!(net.hosts().collect::<Vec<Ipv6Addr>>(), vec![
    "fd00::".parse::<Ipv6Addr>().unwrap(),
    "fd00::1".parse().unwrap(),
    "fd00::2".parse().unwrap(),
    "fd00::3".parse().unwrap(),
]);

Returns an Iterator over the subnets of this network with the given prefix length.

Examples
let net: Ipv6Net = "fd00::/16".parse().unwrap();
assert_eq!(net.subnets(18).unwrap().collect::<Vec<Ipv6Net>>(), vec![
    "fd00::/18".parse::<Ipv6Net>().unwrap(),
    "fd00:4000::/18".parse().unwrap(),
    "fd00:8000::/18".parse().unwrap(),
    "fd00:c000::/18".parse().unwrap(),
]);

let net: Ipv6Net = "fd00::/126".parse().unwrap();
assert_eq!(net.subnets(128).unwrap().collect::<Vec<Ipv6Net>>(), vec![
    "fd00::/128".parse::<Ipv6Net>().unwrap(),
    "fd00::1/128".parse().unwrap(),
    "fd00::2/128".parse().unwrap(),
    "fd00::3/128".parse().unwrap(),
]);

let net: Ipv6Net = "fd00::/16".parse().unwrap();
assert_eq!(net.subnets(15), Err(PrefixLenError));

let net: Ipv6Net = "fd00::/16".parse().unwrap();
assert_eq!(net.subnets(129), Err(PrefixLenError));

Test if a network address contains either another network address or an IP address.

Examples
let net: Ipv6Net = "fd00::/16".parse().unwrap();
let net_yes: Ipv6Net = "fd00::/17".parse().unwrap();
let net_no: Ipv6Net = "fd00::/15".parse().unwrap();
let ip_yes: Ipv6Addr = "fd00::1".parse().unwrap();
let ip_no: Ipv6Addr = "fd01::".parse().unwrap();

assert!(net.contains(&net));
assert!(net.contains(&net_yes));
assert!(!net.contains(&net_no));
assert!(net.contains(&ip_yes));
assert!(!net.contains(&ip_no));

Aggregate a Vec of Ipv6Nets and return the result as a new Vec.

Examples
let nets = vec![
    "fd00::/18".parse::<Ipv6Net>().unwrap(),
    "fd00:4000::/18".parse().unwrap(),
    "fd00:8000::/18".parse().unwrap(),
];
assert_eq!(Ipv6Net::aggregate(&nets), vec![
    "fd00::/17".parse::<Ipv6Net>().unwrap(),
    "fd00:8000::/18".parse().unwrap(),
]);
